Some bacteria produce chemicals that provide food with a certain taste. What word is the same for all bacteria found in Section II?Ħ. The word “staphylo-” when placed in front of a bacterium name must meanĥ. The word “strepto-” when placed in front of a bacterium name must meanĤ. The word “diplo-” when placed in front of a bacterium name must meanģ. This word refers to the shape of a bacterium. What part of the word is the same for all bacteria found in Section I? Section III Treponema palladium (Syphilis) Questions and Conclusionsġ. Large in size- Streptococcus pyogenes (Tonsillitis)ī’-small in size- Streptococcus lactis -(Buttermilk)į-with hairs (flagella)- Bacillus typhosa (Typhoid fever)į’-with a bulge (spore) in the middle- Bacillus botulinum (Botulism poisoning) f”-with aīulge at the end- Bacillus tetani (Tetanus) With a heavy cover (capsule)- Diplococcus pneumoniae (Pneumonia) b. Section IĪ-without a heavy cover- Diplococcus meningitidis (spinal meningitis) a’. If the general shape of a bacterium is spiral, go to III, skip II and I. If the general shape of a bacterium is rod (long and straight), go to II, skip I and III. If the general shape of a bacterium is round, go to I, skip II and III. 85 Shapes of Bacteria 31 LABORATORY MANUAL Chapter 16 FIGURE 1Ĭopyright © Glencoe/McGraw-Hill, a division of The McGraw-Hill Companies, Inc. Identify and label each bacterium in FIGURE 1. Label each bacterium in Data and Observations. The key also lists in parentheses the disease caused by the bacterium or type of food in That describes its shape in scientific language, and a last name that may also describe some specialĬharacteristic. The key will allow you to identify each bacterium by name. Start at the top, following theĭirections. Use the key to identify each type of bacterium (singular for bacteria). Examine FIGURE 1 in Data and Observations, which shows bacteria magnified 2000 times theirĢ. You will discover a process of elimination or “key” that will be used to help in the identification. You will identify bacteria by using their shape and other characteristics as clues. Small? One way is by their characteristic shapes, or patterns of joining together in groups. How can a scientist tell those organisms apart when they are so Thousands of different types of bacteria are known and have been observed, and there are possibly many
